If it is determined to be "S", this routine ends without any particular processing. On the other hand, if "NO" is determined, the process proceeds to step SP4, and the screen of the display 202 is switched to the screen corresponding to the screen switching key.

Further, each operator (key, volume operator, etc.) on the operation panel may be associated with the screen on the display 202. That is, the operators of the dynamics unit 300, the equalizer unit 350, and the effect plug-in unit 450, which are provided with the display keys 302, 352, 452, respectively, are displayed when the display keys 302, 352, 452 are pressed. It is associated with the screen to be displayed. Here, a plurality of operators associated with the same screen form a "display group". On the other hand, a portion where the display key is not provided, for example, each key in the layer unit 500 is not associated with the screen, and therefore does not belong to any display group.

In this embodiment, it is possible to set, for each display group, whether or not to automatically display the corresponding screen when the operator associated with the screen is operated. . That is, the RAM 218 stores the “interlocking flag” for each display group, and the interlocking flag is set to “1” when the screen should be switched in association with the operator, and the screen should not be switched when the screen should be switched. Has the interlocking flag set to "0".

FIG. 15B shows a routine executed when each operator is operated. When the process proceeds to step SP12 in the figure, it is determined whether or not the interlocking flag is set to "1" in the display group to which the operator belongs. If "NO" is determined here,
The process proceeds to step SP18, and the process (parameter change, etc.) corresponding to the operator is executed. If the operated operator does not belong to any display group, it is always determined as "NO" in step SP12, and similarly step SP18 is executed.

On the other hand, if the interlocking flag is set to "1" for the display group to which the operator belongs, "YES" is determined in step SP12 and the process proceeds to step SP14. Here, it is determined whether or not the screen corresponding to the display group is already displayed on the display device 202. If "YES" is determined here,
Since it is not necessary to switch the screen, the process proceeds to step SP18. On the other hand, if the corresponding screen is not displayed, the process proceeds to step SP16, and the screen corresponding to the display group to which the operator belongs is displayed on the display 202. Then, when the process proceeds to step SP18, the process corresponding to the operator is executed. here,

When 9 is pressed, the pair setting screen 650 shown in FIGS. 10A and 10B is displayed on the display 202. Where "pair"
Means two channels in which various parameters work together when forming a stereo audio signal. In the present embodiment, either of the “horizontal (HOLIZONTAL) mode” and the “vertical (VERTICAL) mode” can be selected as a mode (pairing mode) forming a pair. Here, the horizontal mode is a mode in which pairs are formed in the order of channel numbers.

In the horizontal mode, for example, as shown in FIG.
As shown in, the first input channel and the second input channel form a pair, and the third input channel and the fourth input channel form a pair. The vertical mode is 2
In one layer, the corresponding channels form a pair. In the vertical mode, for example, as shown in FIG. 10B, the first input channel which is the first channel of the first layer and the 25th input channel which is the first channel of the second layer form a pair. The second input channel, which is the second channel of the first layer, and the 26th input channel, which is the second channel of the second layer, form a pair. The third
As for the layer and the fourth layer, a pair of vertical modes can be configured similarly to the first layer and the second layer.

In these figures, reference numeral 652 is a horizontal mode switch, and 654 is a vertical mode switch. Either one is selectively turned on to specify any pairing mode. Reference numerals 660 and 670 are left channel display portions, and 661 and 671 are right channel display portions, which display two channel numbers set in a pair. Reference numerals 662 and 672 denote MS (MONORAL / STEREO) mode display portions, which display the MS mode of two channels which are paired. That is, the MS mode display unit 6
When a normal heart symbol is displayed as in 62, the MS mode is “STEREO”, and the MS mode display section 6
When a broken heart symbol is displayed as 72, the MS mode is "MONORAL".

Reference numerals 664 and 674 denote MS mode changeover switches, which are used when the MS mode is set to "STEREO" or "MONORA".
Toggle to set to "L". 682,68
Reference numerals 4 and 686 denote layer switching tags, which are provided for each layer in which the pairing mode or the MS mode is set. The pairing mode can be set independently between the first and second layers and between the third and fourth layers. For example, the vertical mode may be set between the first and second layers, and the horizontal mode may be set between the third and fourth layers.

When the MS mode is set to "STEREO",
Some parameters are shared by the two channels forming the pair. The shared parameters are gate (GATE) settings, insertion effect settings,
Attenuation (set by volume operator 358), equalizer settings, compressor (COMP) settings,
Channel on / off, fader amount, AUX output channel pre-fade or post-fade,
These are ON / OFF of the AUX output channel and AUX output channel level. Also, parameters that are not shared are
The patch status in the input patch unit 112, the presence / absence of phase inversion, the pan status, various patch statuses, and the like. Regarding pan, in addition to the MS mode setting, the paired channels are linked in the same or opposite directions (GANG).
Called) is configurable.

When the pairing mode is set to "vertical mode", one stereo channel (two channels in monaural conversion) can be assigned to one fader.
Therefore, if all the MS modes of the pair of the first and second layers are set to “STEREO”, the volume of stereo 24 channels can be adjusted by 24 faders. On the other hand, if the pairing mode is set to "horizontal mode", one stereo channel is assigned to two adjacent faders. Therefore, the number of stereo channels whose volume and the like can be adjusted by 24 faders is limited to "12". When the MS mode is set to "STEREO" in the horizontal mode, when one of the faders forming the pair is operated, the fader position of the other fader is adjusted so that the fader position becomes the same.

2.7. Operation for Fader Operation Next, the process when the fader is operated in the channel strip section 6 will be described with reference to FIG. When the process proceeds to step SP22 in the figure, the states of the MS mode and the pairing mode are determined for the operated fader, and the process is branched according to the result. First, the MS mode of the fader is "MO
If it is set to "NORAL", the process proceeds to step SP24 regardless of the pairing mode of the layer.

Here, the level of the input / output channel corresponding to the operated fader is controlled. That is, as described with reference to FIG. 8, since the layer of the channel strip section 6 is uniquely specified in the layer section 500, when which fader is operated is specified, the input / output channel whose volume is to be adjusted is unique. Is decided. On the other hand, the MS mode of the fader is "STEREO".
If it is set to, the processing to be executed differs depending on the pairing mode.

First, if the pairing mode is the horizontal mode, the process proceeds to step SP26. Here, the input / output channel corresponding to the operated fader and the levels of the adjacent channels forming the pair are adjusted.
At that time, the fader position of the adjacent channel is driven so as to be linked to the fader operated as described above.
On the other hand, if the pairing mode is the vertical mode, the process proceeds to step SP28. Here, the level of the input / output channel corresponding to the operated fader and the level of the channel forming the pair (that is, the corresponding channel in the adjacent layer) are adjusted. In addition, between channels that make up a pair, the level (fader amount) by the fader
Not only that, but the parameters (gate settings, insertion effect settings, equalizer settings, etc.) that were explained earlier to be shared when "STEREO" was set are all linked.

3. Effects of Embodiment As described above, according to this embodiment, the following effects can be obtained. First, in the present embodiment, it is possible to set whether to switch the display of the display device 202 according to the operation of various operators according to the interlocking flag (FIG. 9). As a result, if the interlock flag is set to "1", the operator does not need to perform any particular operation to switch the display, so that the mixing console can be operated efficiently.

On the other hand, there are cases where the operator does not want to switch the screen. As an example, the equalizer unit 35
Suppose that the frequency characteristic of an input channel is adjusted by operating 0. The purpose of operating the equalizer unit 350 is to set the sound quality of the input channel to an optimum state. Therefore, if the operator has the skill to adjust the output sound to the optimum state by listening, the equalizer adjustment screen 900 may be displayed on the display unit 202.
Need not be displayed on the screen, but rather it is preferable to keep other useful information displayed.

As described above, whether or not the related screen is displayed on the display 202 when the operator is operated varies depending on the type of the operator, the skill of the operator, the situation of the concert hall, and the like. It is a thing. In the preference screen 600 of the present embodiment, whether or not the screen is linked to the operator can be arbitrarily set for each display group, so that it is possible to provide the operator with an optimal display state according to the situation. .

Further, in the present embodiment, FIG.
As described in (a) and (b), the horizontal mode and the vertical mode can be set for each layer as the pairing mode. When the pairing mode is set to the “vertical mode”, the limited number of faders in the channel strip section 6 can be effectively used.

However, even with a pair of audio signals in which the MS mode is set to "STEREO", the left and right volume balance may be lost, and the operator intentionally loses the left and right volume balance. There is also a possibility. In consideration of such a case, it is advantageous to use the horizontal mode as the pairing mode. This is because when the operator senses a loss of stereo balance, or when he / she intentionally tries to destroy it, the MS mode is switched to “MONORAL” and the two faders are used to adjust the volume of the two channels individually and simultaneously. Because it can be adjusted.

After all, how to set the pairing mode depends on the difference between the required total number of input channels and the number of faders, whether the left and right volume balance of the stereo input source is stable, and the like. Will be different. In the present embodiment, the pairing mode can be selected based on such a comprehensive viewpoint, and as a result, the pairing mode with the highest operability can be selected.

4. Modifications The present invention is not limited to the above-mentioned embodiment,
For example, various modifications are possible as follows. (1) In each of the above-described embodiments, various functions are realized by the program operating on the mixing console, but only this program is distributed by being stored in a recording medium such as a CD-ROM or a floppy (registered trademark) disk. ,
Alternatively, it can be distributed through a transmission line.

(2) In the above embodiment, an example in which the present invention is applied to a mixing console has been described. However, the present invention is not limited to the mixing console and can be applied to various electronic musical instruments, desktop music programs, etc. You may apply.

(3) Further, in the above embodiment, pairing is performed with two channels as one set, but pairing may be performed with three or more channels (for example, four channels) as one set.
